Thames Water, which is currently blasting the fatberg with high-pressure hoses and pumping it out of the sewer, now plans to turn it into environmentally friendly biodiesel. ‘Even though they are our worst enemy, and we want them dead completely,’ a company spokesman says, ‘bringing fatbergs back to life when we do find them in the form of biodiesel is a far better solution for everyone.’

Once the ‘evil, gut-wrenching, rancid blob’ has been sifted for horrible things you shouldn’t flush, it will end up producing enough energy to power 350 Routemasters for a day. So everyone’s a winner… except the Museum of London, which was hoping to turn a slice of the fatberg into London’s grossest tourist attraction. Maybe next time, eh?
